MORRIS MATTSON, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN EN EMA-SYRING ES.

Specification forming part of Letters Patent No. 33,747, dated November 19, 1861.

To all whom it may concern:

Be 1t known that I, MORRIS MATTSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and usefullmprovementsin Encina-Syringes, I of which the following is a full, clear, and eX- d'escriptiou, reference being had to the accompanying drawings, making part of this specitcation,in which is represented a syringe, the india-rubber tubes being shown in full lines and the bag and other parts in section.

In the class of enema-syringes in which an elastic india-rubber bag (A of these drawings) Y Y is used to pumpthe liquid through the syringe a button or knob 1I on the end ot` the metal pipe a.. This does not at all times make a suiciently tight and secure connection. At the upper end of the bag A is shown my irnproved connection, Where the pipe f, by which the rubber tube g is connected with the bag A, is secured to the bag in such a manner that the joint will be tight, While the pipe f and tube g may be readily removed from the bag when required. A metal plugm hasa button or head 5 and a screw-shank 6 of less diameter than the head. A hole 7 passes longitudinally through the plug. The pipef has a female screw cut in it which lits over the screw G, and when screwed on, as shown in the drawings, the end of the pipe at 8 presses on the rubber bag and clasps it tightly between the end of the pipe and the head 5 ot' the plug m, making a perfectly tight joint.

Vhen the bag A is formed, as here shown, with a neck e and a pipe is to be attached to each end of it, the plug m maybe introduced through the neck of the bag and be pushed by a stick or proper tool through ahole made in the opposite end of the bag just large enough to allow the shank to pass, but not the head 5 of the plug, and when the attachment is to be made at both ends in a similar manner the bag A should be formed without the neck e, both ends of it being rounded off alike, When the button 5 of the plug m may be forced through a hole in the end of the bag, leaving the screw-shank 6 projecting, over which the pipe may be screwed, as before stated. This gives a neat and Workmanlike finish to the syringe, while it has the desired effect of making a tight and durable connection. Vhat I claim as my invention, and desire to secure by Letters Patent, as an improvement in elastic-bag enema-syringes, is-

The above-described connection, consisting of the perforated screw-plug m, onto which the connecting-pipe screws, confining the bag between the pipe and the head 5 of the plug, in the manner substantially as described.

MORRIS MATTSON.
